stored faults:
The fault is declared present after a road test.
Check the connection and condition (possible wiring damage) of the connectors ofcomponents 1 094and150.
Iftheconnector is faulty (seeTe chnical Note 6015A, Repairing e lectrical wiring, Wiring: Precautions for repair),
repair the connector, otherwise replace the wiring.
Ch eck the insulation and continuity ofconnections 4Sand4Tbetweencomponents 150and1094.
Alsocheckthe insulationbetween these 2 connections.
Iftheconnection or connections are faulty (seeTe chnical Note 6015A, Repairing e lectrical wiring, Wiring:
Precautions for repair), repair the wiring, otherwise replace it.
Inspect the condition of the target ( metallic contamination etc.).
Cleanthetarget with compressed air if necessary.
For v ersions e quippedwithdiscbrakes:
Check the sensor/target air gap through one wheel revolution (0.1 mm If the air gap isincorrect:
–Replace the instrumented bearing/wheel sensor mounting assembly (see MR 411, Mechanical, 33A, Rear axle
components, Rear hub carrier bearing: Removal - Refitting).
If the air gap iscorrect:
–Swap both rear wheel brake discs as well as the brake pads.
–Clear the computer fault memory.
–Carry out a road test followed by another check with the diagnostic tool.
–If the fault initially declared as DF007 Rear left-hand wheel speed sensor circuit has become DF027, replace
the instrumented bearing/wheel sensor mounting assembly (see MR 411, Mechanical, 33A, Rear axle
components, Rear hub carrier bearing: Removal - Refitting).
–If the fault remains on the same side, replace component 150 (see MR 411, Mechanical, 38C, Anti-lock
braking system, Rear wheel speed sensor, Removal - Refitting).
For v ersions e quippedwithdrumbrakes:
–Swap both rear wheel brake drums.

NOTESPriorities when dealing with a number of faults:
Deal with fault DF026 Front right-hand wheel speed sensor circuit first if it is
present.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present during a road test.
Visually inspect the condition of the axle assemblies (impacts, deformations etc.) and the conformity and good
condition of the tyre mountings (see MR 411, Mechanical, 35A, Wheels and tyres, Tyres, Identification
and Tyre pressure, Identification).
Check that the braking system (condition of brake pads, sealing, sticking, bleed, bearing clearance, etc.) is in good
condition.
Visually inspect the condition of the target (for clogging, metallic contamination, bearing grease, etc.) and clean
using compressed air if necessary.
Check that the wheel speed sensor mounting is in good condition.
Check the sensor/target air gap through one wheel revolution (0.4 < front wheel air gap < 1.7 mm).
If the air gap is incorrect:
–Replace the instrumented bearing/wheel sensor mounting assembly if necessary (see MR 411, Mechanical,
31A, Front axle components, Hub carrier bearing: Removal - Refitting).
If the air gap is correct.
–Swap both front wheel speed sensors.
–Clear the computer fault memory.
